DOOR JACK.

Application filed April 26, 1924. Serial No. 709,255.

To all whom it may concern:

Be it known that I, EDGAR D. STUBBS, a citizen of the United States, anda resident of Detroit, in the county of Wayne. and State of Michigan,have invented certain new and useful Improvements in Door Jacks, ofwhich the following is a specification.

The object of the invention is to provide a door jack which may be usedfor steadying a door while putting on a lock or for other purposes, andwhich will hold the door at the desired elevation and angle.

Another object is to provide a door jack having the foregoing enumeratedadvantages and capacities and which is also of simple and durableconstruction, reliable and convenient in operation and easy andcomparatively inexpensive to manufacture.

Other objects and advantages of the invention reside in certain novelfeatures of the construction, combination and arrangement of parts whichwill be hereinafter more fully described and particularly pointed out inthe appended claim, reference being had to the accompanying drawingsforming part of this specification, and in which:

Figure 1 is a perspective view of the door jack in position to steady orelevate the door- Figure 2 is a bottom plan view of the door jack; and

Figure 3 is a view in side elevation, showing the door jack in theintitial and final stages of its operation.

Referring to the drawings, the numeral 10 designates a door engaginglever which is of elongated form and longitudinally curved so that theends of the lever rise above the central portion thereof. The under sideof the central portion is serrated or roughened, as indicated at 11 tobetter adapt this central portion to frictionally engage the floor andconstitute the fulcrum of the lever. The upper side of one end of thelever is serrated or roughened, as indicated at 12, so as to be adaptedto frictionally engage the door to be steadied or elevated.

A foot operated member 13 is provided and is pivotally connected, as at14, to one end of the lever 10. The upper side of the member 13 isserrated or roughened, as at 15, and the free end of this member has itsunder side beveled, as indicated at 16.

With this arrangement the free end of the lever 10 is inserted below thedoor, as shown in Figure 3, so that the roughened surface 12frictionally engages the door. The foot operated member 13 is thendepressed by the foot so that the lever 10 is rocked about its curvedcentral portion. This throws the end 12 upwardly and consequentlyelevates the door tothe desired extent, as indicated in dotted lines inFigure 3. The roughened surface 11 of the lever 10 frictionally engagesthe floor and prevents slipping and the roughened surface 15 of themember 13 prevents the foot from slipping from the member 13.

I claim:

In a door jack, a door engaging lever comprising an elongated,longitudinally and downwardly curved and substantially rigid bar, saiddoor engaging lever having the upper side of its free end roughened andalso having the under side of its central portion roughened, the centralportion of the under side being engaged with the floor to provide arocking fulcrum for the door engaging lever, and a foot operated memberpivotally connected to said door engaging lever, said foot operatedmember having its upper side roughened and its free end beveled on theunder side.

EDGAR DAVIS STUBBS.
